I CHARLES BATES, OF SEDALIA, MISSOURI.

PLOW.

SPECIFICATION forming part of Letters Patent No. 239,918, dated April12, 1881.

' Applicationfiled May 31,1880. (No model.)

To all whom at may concern:

Be it known that 1, CHARLES BATES, of Sedalia, in the county of Pettis and State of Missouri, have invented a new and useful Improvement in Plows, of which the followingis a specification.

This invention relates to breaking-plows; and it consists in the construction and arrangement by which the apparatus will form an adjustable gang of two similar breaking-plows without supporting-wheels, and which can he made to act as a subsoiler as well as a single plow.

In my drawings, Figure 1 is a side elevation of my plow. Fig. 2 is a plan or top view of the same. Fig. 3 is an elevation showing a modification of the adjusting device.

Similar reference-letters indicate like parts in all of the figures.

Referring to drawings, A is the plow-beam. B B are the plows, and O the handles of the plow.

To one side of the beam A is attached a second beam, E. Between the two beams A and E is a block, F, which separates the two beams, which are secured together by bolts or rivets F F. The beam E bearsa plow, B, to out a second furrow. The back end of beam E is attached to and held at a proper distance from beam A by part II between them.

The plow B is set a proper distance forward of the plow B to avoid interference with its furrow. Thus, as shown, the two plows throw similar furrows and help to hold each other up properlywithoutrequiring wheels, as is usually the case with gang-plows.

The plows are guided by handles 0 (J, or otherwise. The standards of the plows B B are attached to beams A E, so that the plows may be raised or lowered in relation to their beams and fixed at any required height. The back end of beam A and the handles at I are also correspondingly adjustable.

The standards K K are graduated with horizontal lines to form scales or gages for setting the plows at the desired height for their work. Loops or bands 0, secured to the beams, on the outsides, serve to clasp the standards, and headed clamping-bolts 4 5 serve to hold said standards at given heights.

From the standards K K extend arms L L, which, when clasped to the beams by suitable clampin g-bolts, serve to form braces to hold the plows rigidly to their places when at work.

The upright parts of the arms or braces L L are provided with long slots on, to allow of a free movement of said arms under the heads of the clampin g-bolts which secure them. The

slots to a are provided with rabbet-countersinks to receive the heads of the clampingbolts, which are held against turning when clamped by nuts on the opposite sides of the standard proper passes through a loop between the said arms, and, extending upward, is clamped 'to the loops secured to the said beam. In this modification clamping-bolts may be used also at the point of intersection between the standards proper and the arms extending therefrom.

In subsoiling the plow B must be raised or the one B must be lowered the distance required between the top and bottomfurrows, and the draft-clevis changed from a place between the beams to one before the plow B, so that the plow B will run in the furrow made by the plow B on the previous v passage and throw a furrow from its bottom, while plow B cuts a new furrow to be subsoiled at the next passage.

The beam E and plow B may be removed if required, leaving only a simple single plow.

Having thus described my invention, what I claim as new, and desire to secureby Letters Patent, is-

l. The plow B, provided with astandard having braces L and arm K extending therefrom, the former of which are provided with slots to receive bolts to clamp said arms L to the plowbeam at any desired height, and the latter provided with a graduate or scale, as and for the purpose specified.

2. The combination of the plow provided with a graduated standard and arms to serve as braces extending therefrom, the beam A, handle 0, and loop I, all arranged as and for the purpose set forth.

CHARLES BATES.
